Summary

In this chapter, we've discussed the preliminaries of this book, the machine architecture of modern CPUs, and the way loads and stores of memory may be interleaved for surprising results, illustrating the need for some kind of synchronization for our computations. That need for synchronization will drive much of the discussion of this book. We also discussed installing Rust, the channels of the compiler itself, and our intention to focus on the stable channel. We also compiled a simple program for both x86 and ARM systems. We also discussed debugging and performance analysis of our simple program, mostly as a proof-of-concept of the tools. The next chapter, Chapter 2, Sequential Rust Performance and Testing, will explore this area in much more depth.
